Try the latest alpha version--go to
http://www.neuron.yale.edu/neuron/install/install.html
then click on the link
Snapshots of alpha versions
and select the appropriate installer for your OS. Let me know if that fixes the problem.

Suffix notation varname_mechanismname is only for distributed mechanisms. Point processes are class definitions, and individual instances of a point process use dot notaion objrefname.varname to access parameters and variables. Read chapter 5 of The NEURON Book, or at least read Hines, M.L. and Carn...

Sorry I didn't examine the code you posted on April 17 in any detail prior to today. There were far more fundamental issues at hand then, e.g. the form of the mass balance equation for calcium, whether it made sense to split the intracellular pool of calcium into different subsets according to which...

Re: Assigning to multiple segments at once
Going a bit further, it might also be nice to be able to do: dlist = (0.1,0.2,0.3,0.4,0.2) soma.diam = dlist which would be equivalent to: for i in range(soma.nseg): soma.segments[i].diam = dlist[i] Would this syntax produce the following relationship between nseg and the variation of diam along th...

I was able to reproduce the problem with 5.8.88. It was fixed in the alpha version I picked up from the CVS repository late last week. I see that a new set of alpha version installers is now available; why don't you get one of those from http://www.neuron.yale.edu/ftp/neuron/versions/alpha/ and see ...

Correct. A class definition that is written by the CellBuilder includes a public
procedure called position() that can be used to specify the location of any
cell instance. For example,
procedure called position() that can be used to specify the location of any
cell instance. For example,
Code: Select all
objref pyr4
pyr4 = new L4pyr()
pyr4.position(10, 20, 30) // desired coords of 0 end of root section (soma)

The first and most important tool for reducing model complexity is judgement, guided by experience and a thorough knowledge of the experimental basis for the model in question. There have been a few papers on the topic of model simplification; you might start by reading this one: Bush, P.C. and Sejn...
